The console escape code standard (ECMA-48) specifies color #3 (escape
code 33) as yellow. A brown console color is an artifact of the VGA
palette, which replaces dim (but not bright) yellow with brown.

For historical reasons console color number 3 may be either yellow (most
consoles) or brown (VGA palette). The console escape code standard
uses "yellow", but teken color name constants appear to be based on the
VGA scheme and use TC_BROWN for color 3. Even so, the palette table
used 50,50,0 as the RGB percentage tuple, resulting in a dim yellow for
framebuffer consoles at the time teken was introduced.
Amusingly, in 19e2ce2d83 the comment on the palette entry was changed
from "brown" to "dark yellow" but the colour itself was changed from
a pure yellow to being somewhat brown.

If module_verbose is set to a value below MODULE_VERBOSE_TWIDDLE
call twiddle_divisor(UINT_MAX).
This makes more sense here than when we are loading the kernel.

UEFI provides a protocol for accessing randomness. This is a good way
to gather early entropy, especially when there's no driver for the RNG
on the platform (as is the case on the Marvell Armada8k (MACCHIATObin)
for now).
If the entropy_efi_seed option is enabled in loader.conf (default: YES)
obtain 2048 bytes of entropy from UEFI and pass is to the kernel as a
"module" of name "efi_rng_seed" and type "boot_entropy_platform"; if
present, ingest it into the kernel RNG.

Set module_verbose to control the printing of information
about loaded modules and kernel:
0 MODULE_VERBOSE_SILENT None
1 MODULE_VERBOSE_SIZE Pathname and size
2 MODULE_VERBOSE_TWIDDLE as for 1 but also twiddle for progress
3 MODULE_VERBOSE_FULL extra detail
When the loader is verifying modules we already have a
running indication of progress and module_verbose=0 makes sense.

Shortlinks occupy the space of both di_db and di_ib when used. However,
everywhere that wants to read or write a shortlink takes a pointer do
di_db and promptly runs off the end of it into di_ib. This is fine on
most architectures, if a little dodgy. However, on CHERI, the compiler
can optionally restrict the bounds on pointers to subobjects to just
that subobject, in order to mitigate intra-object buffer overflows, and
this is enabled in CheriBSD's pure-capability kernels.
Instead, clean this up by inserting a union such that a new di_shortlink
can be added with the right size and element type, avoiding the need to
cast and allowing the use of the DIP macro to access the field. This
also mirrors how the ext2fs code implements extents support, with the
exact same structure other than having a uint32_t i_data[] instead of a
char di_shortlink[].

On boot we don't need to perform any CPU cache management when the IDC
and DIC fields in the ctr_el0 register are set. Add a command to tell
loader to ignore these fields. This could be useful, for example, if the
hardware is misreporting the values and we are missing a quirk to enable
it.
It is not expected this will be needed, but is only intended as a
workaround to ensure the kernel can still boot.

When we load an ELF file (kernel or module) we do seek(2) a lot to
parse/load the different sections of the ELF file.
Protocol like TFTP suffers a lot from this as there is no resume or
a way to start the tranfer from a specified offset in the file.
fs_preload is added to help those protocol.
Call preload just after opening the ELF file that we need to load so
the underlying method can cache the hole file and then read/lseek operations
are faster.
